CAUTION
In the system where all indoor units are
running at the same time, the total capacity of
the indoor units should be less than or equal
to the combined capacity of the outdoor unit
to prevent overloading in bad working
conditions or narrow operating space.
If the system is applied in a cold region
(ambient temperature is -10°C and below) or
a very hot, heavy loading environment, the
total capacity of the indoor units should be
less than the combined capacity of the
outdoor unit.
Note:
1.The maximum quantity of connected indoor units
depend upon indoor unit type and total combination
ratio.
